A TTORNE Patented Oct. 15, 1929 UNITED STATES MARK KIRIN, OF DETROIT,MICHIGAN VEHICLE RADIATOR CA1? Application filed Novemberzl, 1927.

My invention relates to a new and useful improvement in a vehicleradiator cap, and has for its object the provision of a radiator capadapted for use on vehicle radiator necks.

'5 With vehicle radiators as now commonly used on passenger cars theradiator neck is formed of one of two sizes, being either interiorly orexteriorly threaded, the size of either class being always the same.

It is an object of the present invention to provide a radiator cap whichmay be used on either type of radiator neck.

It is another object of the present invention to provide a radiator capwhich may he used on either type of radiator neck and which will effecta tight and firm sealing of the radiator neck by the cap.

It is another object of the present invention to provide a universalradiator cap of this class in which the cap may be swung on itsmountings on the neck so that an unthreading of the cap in order toreplenish the water in the radiator will be unnecessary, thusfacilitating the filling of the radiator and obviate the diflicultiesoften encountered in unt-hreading a radiator cap, particularly when thewater has become heated and there is a steam pressure in the radiator.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of partshereinafter described. and claimed.

The invention will be best understood by a reference to the accompanyingdrawings which form a part of this specification and in which,

Fig. 1 is a side elevational view of the invention mounted on a radiatorneck.

Fig. 2 is a front elevational view of the in vention mounted on aradiator neck.

Fig. 3 is a sectional view taken on substantially line 33 of Fig. 2.

Fig. 4 is a sectional view taken on line 4l4l of Fig.3.

In the drawings the radiator 7 is illustrated with an exteriorlythreaded neck 8. The invention comprises a ring 9 which is interiorlyand exteriorly threaded and provided on its upper end with an exteriorflange 10 to provide a shoulder for engaging the gasket 11.

Serial No. 234,605.

adapted to engage a lug 22 on the cover 17 and lock the cover 17 inclosed position.

When the ring 9 is threaded on to the neck 8 the gasket- 13 will beengaged by the upper edge of the neck 8 and thus a leak proof connectionof the ring 9 on the radiator neck 8 provided, so that the water in theradiator is prevented from reaching thethreads of the ring 9 andconsequent rusting thereof prevented. When the cap 17 is swung to closedposition the gasket 19 will be brought into engagement with theuppersurface of the flange 12, so that a leak proof cap is afforded at thisparticular point.

Should it be desired to use the cap on an interiorly threaded neck, itis evident that the gasket 11 would in that instance be compressed bythe upper edge of the radiator neck and the gasket 19 would function asillustrated, for sealing purposes.

In this way I have provided a radiator cap which is simple in structure,easily and quickly mounted, universal as to its use, whether it be on aninteriorly or eXt-eriorly threaded neck, and one which affords a tightsealing of all places where leakage might occur.

While I have illustrated and described the preferred form of myinvention, I do not wish to limit myself to the precise details ofstructure shown, but desire to avail myself of such variations andmodifications as come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. As an article of manufacture a radiator cap of the class described,comprising: an annular member having its interior and its exteriorthreaded; a radially projecting flange at one end projecting interiorlyand exteriorly, said annular member being threadable upon a radiatorneck; a gasket positioned in engagement with said flange, said gasketengaging between said radiator neck and said flange for effecting asealing; and a cover swingably mounted on said annular member.

2. As an article of manufacture a radiator cap of the class described,comprising: an annular member having its interior and its exteriorthreaded; a radially projecting flange at one end projecting interiorlyand exteriorly, said annular member being threadable upon a radiatorneck; a gasket positioned in engagement with said flange, said gasketengaging between said radiator neck and said flange for effecting asealing; a cover swingably mounted on said annular member; and a gasketengageable with the upper surface of said annular member and the innersurface of said cover at the inner side of said annular member foreifecting a sealing.

3. As an article of manufacture a radiator cap of the class described,comprising: an interiorly and exteriorly threaded ring; an interiorflange at one end of said ring; an exterior flange at said end of saidring, said flanges forming abutment surfaces; a gasket for engaging saidabutment surfaces; a cover swingably mounted on said ring; and a gasketengageable with the inner surface of said cover and the inner edge ofsaid ring for effecting a sealing.

4. As an article of manufacture a radiator cap of the class described,comprising: an interiorly and exteriorly threaded ring; an interiorflange at one end of said ring; an exterior flange at said end of saidring, said flanges forming abutment surfaces; a gasket for engaging saidabutment surfaces; a cover swingably mounted on said ring; a gasketengageable with the inner surface of said cover and the inner edge ofsaid ring for effecting a sealing; and means for clamping said cover inclose engagement with said gasket.

In testimony whereof I have signed the foregoing specification.

MARK KIRIN.
